C3, C4, and CAM plants. C4 plants are more productive in hot and dry climates than C3 products because they use 3-fold less water and can grow in conditions of drought or high temperature. The difference between C3 and C4 plants. The main difference between C3 and C4 plants is, C3 plants uses the C3 pathway and majority of plant son this Earth are C3 plants, while on the other hand, C4 plants uses the C4 pathway. The main difference between C3 C4 and CAM photosynthesis is that C3 photosynthesis produces a three-carbon compound via the Calvin cycle, and C4 photosynthesis produces an intermediate four-carbon compound, which split into a three-carbon compound for the Calvin cycle, whereas CAM photosynthesis gathers sunlight during the day and fix carbon dioxide at night. RuBP can accept CO2 in both C3 and C4 plants. C3 plants provide a higher amount of protein than the C4 plants. 7. It occurs in grasses, sugar cane, maize, sorghum, Amarathus and Atriplex.C 4 cycle is the alternate pathway of Calvin cycle (C 3 cycle) taking place during dark phase of photosynthesis. Biology is brought to you with support from the Amgen Foundation. C4 plants have a process that allows them to use CO2 down to a much lower level than C3 plants. The main difference between C3, C4 and CAM plants is the way these plants minimize water loss. In fact, there's even a plant called Agave Angustifolia that switches back and forth between modes as the local system dictates. Unlike C4 plants, C3 plants reduce into carbon dioxide directly in the chloroplast. C 4 plants live in hot moist or arid and nonsaline habitats. “That means that C4 plants are typically better adapted to hot weather and drought just because of that simple process of closing off the stomata and restricting gas exchange,” says Brenzil. 6. Sort by: Top Voted. Practice: Photorespiration. Photosynthesis is the process that plants use to turn light, carbon dioxide, and water into sugars that fuel plant growth, using the primary photosynthetic enzyme Rubisco. The carbohydrate product of both C3 and C4 cycle is a three-carbon sugar phosphate molecule known as Glyceraldehyde 3 phosphate (G3P). C3, C4 and CAM are the three different processes that plants use to fix carbon during the process of photosynthesis.Fixing carbon is the way plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates. Up Next. C 4 plants: The plants exhibiting C4 pathway are called C4 plants. Difference between C3 and C4 Cycles of Photosynthesis in Plants Calvin Cycles vs Hatch and Slack Cycle Photosynthesis is one of the vital events in the earth in which the green plants fix the energy from the sunlight and synthesis nutrients with carbon dioxide and water. Definition of C4 pathway or Hatch and Slack pathway. Some C4 plants also function at least partially in C3 or C4 mode. C3 plants have denser topology than C4 plants. All of these plants are able to adapt to arid, high heat and light environmental conditions. C4 plants are less than C3 but they are efficient in carrying out the process of photosynthesis. They are highly proteinaceous than the C4 plants. 5. The examples of annual C3 plants are wheat, oats, and rye and the perennial plants include fescues, ryegrass, and orchardgrass. Both C3 and C4 plants fix energy from sunlight. The C3 plants can be perennial or annual. This is the currently selected item. Photorespiration. Photorespiration. 4. Species: Cactuses and other succulents, Clusia, tequila agave, pineapple. Both C3 and C4 plants require 6 molecules of CO2 and 12 molecules of water to synthesis one molecule of glucose.
